My invention relates to a new and useful improvement in a vehicle brake and has for its object the provision of a brake which may be used on all four wheels of the vehicle or on only two of the wheels ofthe vehicle, as desired.

It is an object of the present invention to provide a brake which will be easily and quickly operated and efcient in the maxi- 1o mum degree.

Another object of the invention is vthe provision of an axially movable friction member en ageable with a stationery member for bra ing purposes. j

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter: described and claimed.

The invention will be best understood by a reference to the accompanying drawings which forms a part of this specification, and in which, v

Fig.v 1 is a central vertical sectional of the invention. v

Fig. 2 is a view taken on line 2--2l of Fig. 1.

Fig. 3 isaV fragmentary view taken on line 3 3 of Fig. 1.

Fig. 4 is a fragmentary view taken on line 4 4 of Fig. 1.

In the drawings I have illustrated a vehicle wheel 8 as mounted on the spindle 7. Pins 9 are projected through the hubflange of the wheel and provided with a collar 10 and a projecting kvendV 1l which vprojects through the disc 12 which has a peripheral Harige axially extended and angularly turned as at 13.l A flange block carrying the plate 14 is mounted on the disc 12 and carries yieldable friction engaging members 15, formed from cork or other suitable material. These members 15 are preferably cylindrical in form and are projected. in a press fit, through openingsk in kthe disc 12. Mounted on the knuckle 16,- which serves to attach the spindle 7 to thek axle 17 is a brake drum 18 against which the members l5 are adapted to engage when'- used for braking purposes. A peripheral axially extended flange 19 is provided on the view drumfan'd secur'edto and projecting outwardly from the flange 19'are bearing brack ets-20 in `which is rockably mounted thel bight 21 of the U-shaped member, 'the longer le'g22 of which is connected to the 55 operating rod 24 having the U-shaped portion 25 intermediate its ends and connected toa suitable operating rod 26.? A collar23 is mounted onthe otherleg ofthe U-shaped member.V y f .5

In operation a'pullingor a pushing on the rod 26, depending uponl the installation, will effect a rocking ofthe leg 22 so as to bring the collar 23 into engagement with the iange 13 and force the engagement 65 members 115 into engagement with the drum 18, this ,drum beingstationary `and the disc 12 rotating with the wheel. It is obvious that in this operation the disc 12 is moved axially toward thejdrum 18 and slides on 70 the pins 11. Y V

In this way there is provided a device whereby a` braking over a large area may be effected and an efficient retarding of the rotation of the wheel quickly effected The simplicity ofthe device is believed apparent as well as the economy of manufacture.

While I have illustrated and described` the preferred form of my invention, I do not wish to limit myself to the precise details of structure'shown but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A vehicle brake of the class'described comprising: a supporting'member mounted on and rotatable with and axially moveable of a vehicle wheel; av disc mounted on said supporting member; a plurality of spaced yieldable'friction members mounted on said disc; a stationary engagement member for engaging said friction members upon movement of said supporting member axially of said wheel in one direction; `and rockable means engageable with said supporting member adjacent its periphery for movinr said supporting member axially of sai Wheel in onedireotion; and means for rocking said rockable means.

2. A vehicle brake of the `class described adapted for use With a rotatably mounted vehicle Wheel comprising a circular disc-like member mounted upon and rotatable With said Wheel7 a portion of said member adjacent its periphery, being axially turned and then angularly turned to provide a radially extending offset portion; a carrying plate mounted on said disc;r friction members` mounted on said carrying membeig'said carrying member and said disc being axially movable relatively to said Wheel; a stationary engagement member vfor engaging saidY friction `members upony movement axially of said .plate and said disc7 a predetermined distance in one direction; and i io'clable means engaging with said radially extending offset portion ofV said disc for,rupon rocking, moving said disc and said carrying member into approach relatively to said stationary engagement member. s Y Y In testimony whereof Il have signed the foregoing speciiication.
